For the posterior exploration we use the numerical code emcee [1]} and for the visualization of the chains the code getdist [2]}.
The convergence of the chains is tested following the method by [3]}, which consists in estimating the effective number of independent samples using the integrated autocorrelation time (which is the mean number of steps needed before the chain forgets where it started).
In the Supplementary Materials we provide plots and convergence tests for all the redshift slices.
In the MCMC exploration, we start the chain from the best-fit model in order to avoid the burn-in phase.
